中文摘要：

利用1950-2005年西北太平洋热带气旋（TC）和赤道中东太平洋表层水温（SST）资料，统计分析了赤道中东太平洋表层水温异常与TC频数、强度、源地和路径等的关系。结果表明，赤道中东太平洋暖异常年：（1）TC发生频数偏少，较常年平均偏少2～3个，但强度偏强，强台风和超强台风发生数偏多，较常年平均偏多1个左右，且随着暖异常强度的增强，TC发生频数偏少，强度增强愈加明显；（2）TC生成位置偏东偏南，145°E以东海区TC生成频数较冷异常年和La Nina年增加明显；（3）TC路径偏东，转向路径出现频次增加，西向路径出现频次减少，从而导致日本东部海区TC通过频数增加，而我国南海和华东沿海TC通过频数减少；（4）在我国登陆的TC频数偏少，较常年平均偏少1～2个。赤道中东太平洋冷异常年，情况基本与上相反。上述影响主要是由于赤道中东太平洋SST异常导致大气环流发生异常造成的。

英文摘要：

By using the tropical cyclone data in north-west Pacific and the sea surface temperature （SST） data, the impacts of SST anomaly in the equatorial central and eastern Pacific on the frequency,in- tensity, formation location and track of tropical cyclone（TC） were analyzed. The results indicate that the TC occurrence numbers and the landing TC numbers are less, the TC intensity is stronger, the TC formation location and the center of the maximum value of TC passage frequency are more eastward and southward, the frequencies of northeastward recurving track and northeastward track are more and the frequencies of northwestward track and westward track are less in warm anomaly years than in cold anomaly years. The stronger the SST anomaly is, the larger the impacts on TC are. In warm anomaly years,TC tend to recurve northward and Japan will be more easily affected by TC than China. The impacts are caused by the change of the atmospheric circulation resulting from the SST anomaly in the equatorial central and eastern Pacific.
